Product Details

This combo pot and rotary switch bypasses your instrument's volume and tone controls. Play full throttle, with the pickup wired directly to the output jack, for a broader signal and enhanced highs.

"Take the muffler off your electric guitar!"
—Ned Steinberger, designer

When wired into your guitar (rewiring of tone controls may be required), this control removes the load of the pots. Think of it as a knob that goes from 0-10, plus a switch to 11—there's an actual click!

The JackPot's rotary switch clicks on when the knob reaches full rotation. The open switch lifts the ground to the pot, eliminating the load on the pickups and letting the full signal reach the output jack. When the knob is rotated counterclockwise, the ground to the pot is reconnected, so the pot returns to standard operation.

"On my Tele I get a brighter, more aggressive sound that is more sensitive to my picking style and attack!"
—Casey Davis, guitarist and StewMac customer service rep

Why do you want it?

  • With the JackPot you can play full on, with the pickups wired directly to the output jack. You'll still have a trusty volume knob to back off instantly to a lower level when needed.
  • The JackPot produces a stronger signal level, greater warmth, more intensity.
  • On typical instrument wiring, when the volume knob is maxed out, there is still a portion of the signal that bleeds to ground. The output level never reaches the full level the pickup would achieve if it were wired directly to the output jack.

Which pot value should you choose?
500K pots are standard controls for humbuckers, and 250Ks are usually used for single-coil pickups. A 250K gives a slightly warmer tone than a 500K, and bleeds off some of the high frequencies to ground. A 1-meg pot bleeds off even less than a 500K.

1-meg pots are also ideal for piezo pickups, as the ultra high impedance piezo element is more adversely effected by conventional, lower-value pots than magnetic pickups.

Replacement Mounting Nuts and Lock Washers are also available.

Simple but effective

I've used these on a couple of showcase guitars to demonstrate some fancy wiring options. Really well made, intuitive to use and opens up the tone of your instrument nicely. On a humbucker equipped Jaguar style guitar, I can get a nicely pronounced Tele style twang. It also works really well if you "park" your tone at a favourite position and then use the volume knob to toggle between settings instantly.

I love this thing.

Just put it in a client's guitar, and I thing it's great. Unlike the trad blower switch that just works on the bridge pickup, this one works on all. Good volume and treble boost. Very well made. I'm buying some for my personal instruments.

Fantastic!

I think the previous reviewer missed the whole point of these pots. The only way to get direct injection from the pup is to lift the ground and eliminate the tone pot (high pass bleed to ground). I installed this pot in my latest Tele build, complete with Fender Texas Custom pups, 4-way switching, and a push-pull for tone and diode rectifier circuit. This guitar is a tone machine! Great invention! Upgrading my SG build with these pots, and will be standard in all future builds. . .

Great idea, Poor implementation

These may work if you are using 24 gauge modern wires, but if you use vintage cloth wire only one wire will fit through the tiny holes. I installed this on two Telecasters with 4 way switches and a Stratocaster. If you look at both wiring diagrams they use the same lug for different things and I could not get the Tele diagram to work except for the neck pickup. The Strat diagram works but a vintage Strat needs a tone pot when soloing. I would give it two stars if Steinberger's website had a diagram that correctly labeled all the lugs, but I couldn't find anything except the diagrams here and they are rather random. This needs to be done with a full sized pot and full sized tabs!

Jackpot A Winner

I recently had a 4 way selector switch, and then a Jackpot Volume pot on my Telecaster. Wow! I love it. The volume pot bypasses everything and goes straight to the jack and gives the guitar more oomph. Well done Ned Steinberger! Be aware it is a mini pot and very small. With these two mods done, I am completely satisfied with the whole thing now.

Interesting Device

I recently install one for a friend in a 1992 Fender Prodigy. He said that there is a noticeable boost in volume and brighter tone when engaged. He liked the feature. The only issue that I had was connecting all the ground wires. The terminals would only accept a max of 3 stranded wires and design does not allow you to solder to the metal case of the pot. You then have to connect some or all of the grounds to a single wire and then connect it to the pot. The original wiring used the volume pots case as the common tie point.
